I never try to use it, but I've read it in some articles which I don't exactly sure what site it is, they have called top 6 bot and each bot had their own price of bitcoinBTC according to it functions minimum was 0.01BTC, in fact, I got curious on it, and attempt to try but I realized that doing trade manually is much comfortable than using bot in the trading you cannot appreciate your profit if you use it unlike in manual you appreciate because you are the one made a hard work for it.
